Definitions

  • the invention relates to a method for producing elastic Flexible polyurethane foams.
  • two large product groups are used as soft, elastic, cellular upholstery materials. These are on the one hand the soft elastic polyurethanes and on the other hand the latex foams. There are differences between the two product groups in the starting products, the manufacturing process and the mechanical properties as well as their application.
  • latex foams there is a slightly different course of the compression hardness curve according to DIN 53577 and ISO 3386, parts 1 and 2.
  • polyurethane foams latex foams do not show a pronounced compression hardness plateau, but rather an almost linear increase in compression hardness in a certain compression range. For certain applications, this characteristic is desirable or even fixed.
  • the average bulk density of the latex foams is at least 60 kg / m 3 or mostly higher and this has compression hardness between 3 and 4.5 kPa.
  • Such types of foam are preferably used to manufacture high quality mattresses.
  • Polyurethane foams usually show higher in this bulk density range Compression hardness and also another compression hardness / compression process.
  • these foams are said to have low permanent values Deformation as well as low values after wet aging. This is a particularly important criterion.
  • blowing agents such as hydrofluoroalkanes or alkenes such as Pentane, i-pentane, cyclopentane or carbon dioxide are used become.
  • the filler content, based on the polyol component B) from i) and ii), is 2 to 30, preferably 3 to 15, particularly preferably 3 to 10% filler PHD, SAN or PIPA. Since the filler dispersions ii) generally between 10 and 40% filler manufactured, this must be taken into account accordingly.
  • A is often used Filler content of 20%, so that e.g. at 25 parts by weight ii) and 75 parts by weight i) a filler content of 5% by weight, based on the polyol component B) becomes.
  • Starting materials on the side of the polyols i) are polyols which are obtained by addition of Alkylene oxides such as ethylene oxide and propylene oxide to higher functional starters such as Sorbitol, mannitol or sucrose alone or in combination with starters such as ethylene glycol, Propylene glycol, glycerin, trimethylolpropane or pentaerythritol, so that functionality between 4 and 8 can be set.
  • Alkylene oxides such as ethylene oxide and propylene oxide
  • higher functional starters such as Sorbitol, mannitol or sucrose alone or in combination with starters such as ethylene glycol, Propylene glycol, glycerin, trimethylolpropane or pentaerythritol, so that functionality between 4 and 8 can be set.
  • Starters for the filler polyols ii) are glycerol, trimethylolpropane, pentaerythritol, Propylene glycol and ethylene glycol.
  • Alkanolamine crosslinkers G include compounds such as diisopropanolamine, triisopropanolamine, Triethanolamine, diethanolamine, 2-hydroxyethyl-2-hydroxypropylamine and bis- (2-hydroxyethoxyethyl) amine or mixtures thereof.
  • unmodified polyisocyanates e.g. the 2,4- and 2,6-tolylene diisocyanate as well as any mixtures of these isomers (“TDI”), polyphenylpolymethylene polyisocyanates, as by aniline-formaldehyde condensation and subsequent phosgenation are produced (“raw MDI").
  • Particularly stabilizers F) are polyether siloxanes, preferably water-insoluble ones Representative, in question. These connections are generally structured that a short-chain copolymer of ethylene oxide and propylene oxide with a polydimethylsiloxane residue is connected. Such foam stabilizers are e.g. in U.S. Patents 2,834,748, 2,917,480 and 3,629,308 and U.S. Patent 2,917,480 described.
  • Catalysts F of the type known per se are e.g. tertiary amines, such as triethylamine, Tributylamine, N-methylmorpholine, N-ethylmorpholine, N, N, N ', N'-tetramethylethylene diamine, Pentamethyl-diethylenetriamine and higher homologues (DE-A 2 624 527 and 2 624 528), 1,4-diazabicyclo- (2,2,2) -octane, N-methyl-N'dimethylaminoethylpiperazine, Bis (dimethylaminoalkyl) piperazines, N, N-dimethylbenzylamine, N, N-dimethylcyclohexylamine, N, N-diethylbenzylamine, bis (N, N-diethylaminoethyl) adipate, N, N, N ', N'-tetramethyl-1,3-butanediamine,
  • Organic metal compounds in particular, can also be used as catalysts F) organic tin compounds can be used.
  • organic tin compounds come in addition to sulfur-containing compounds such as di-n-octyl tin mercaptide preferably tin (II) salts of carboxylic acids such as tin (II) acetate, tin (II) octoate, Tin (II) ethylhexoate and tin (II) laurate and the tin (IV) compounds, e.g. dibutyl tin oxide, Dibutyltin dichloride, dibutyltin diacetate, dibutyltin dilaurate, dibutyltin maleate or dioctyltin diacetate.

  • the reaction components are prepared according to that known per se One-step process, the prepolymer process or the semi-prepolymer process implemented, often using machinery, e.g. those described in US Pat. No. 2,764,565. Details about Processing devices that are also suitable according to the invention in the plastic manual, volume VII, edited by Vieweg and Höchtlen, Carl-Hanser-Verlag, Kunststoff 1966, e.g. described on pages 121 to 205.
  • the implementation is usually carried out in a range from 90 to 130.
  • foaming can also be carried out in foam production closed forms.
  • the reaction mixture is in entered a form.
  • Metal e.g. Aluminum
  • Plastic e.g. Epoxy resin
  • the foamable reaction mixture foams in the mold and forms the Moldings.
  • the foam molding can be carried out so that the Has molded part on its surface cell structure. But it can also be done this way be that the molded part has a compact skin and a cellular core receives. According to the invention, one can proceed in this connection in such a way that one enters so much foamable reaction mixture in the mold that the formed Foam fills the shape straight.
  • the foams are preferably produced by block foaming.
  • Polyether polyol of OH number 28 prepared by adding 82% by weight of propylene oxide and 18 wt .-% ethylene oxide on sorbitol as a starter with predominantly primary OH terminal groups
  • the polyol i) according to the invention is replaced by a polyol having an OH number of 28 82% by weight of propylene oxide and 18% by weight of ethylene oxide, but with trimethylolpropane as a starter and predominantly primary OH end groups, you get an unstable Raw material mixture that cannot be foamed in this context.
  • Examples 4 and 5 are produced with a compression hardness of 3.4 or 2.8 KPa with a filler content of 20 or 10% by weight and a bulk density of 30 kg / m 3 on the basis of trifunctional polyols and alkanolamine crosslinking with diethanolamine , result in wet aging values that are between 12 and 15%.
